Abstract

La présente invention concerne un procédé et un dispositif destinés à un appareil de respiration sous l'eau (100) dans lequel un gaz respiratoire est fourni à une boucle de débit (104), à partir de deux sources séparées (110, 112) de gaz; chaque source possède une fraction d'oxygène différente et est commandée par un dispositif, séparé et à débit variable, de régulation de débit massique (120, 122). Les débits massiques peuvent être réglés de manière adaptative afin de fournir un gaz à des débits variables, lesquels dépendent uniquement d'une fonction de la pression ambiante environnante.
